Mentioned this before, but a regulator leak can be difficult to find because of how they are constructed.
Sometimes its just a process of elimination.
IMO, the best way isolate a regulator leak is to remove lines and install a 1/4" threaded plug on the outlet.
Then install it on the tank, pressurize, then close the tank valve.
If the gauges on the regulator don't hold primary or secondary pressure over time, you can be pretty confident that the regulator is where your leak is.
Occasionally a leak will form where a fitting threads into a regulator, but those are usually easy to find with some star-san solution in a spray bottle.
